Enhanced Fast Dormancy 2 Overview



2-1

2 Overview

Some intelligent UEs on a live network send a Signaling Connection Release Indication (SCRI) message to the RNC after PS data transmission is complete. By sending the SCRI message, intelligent UEs request for a transition to idle mode or the CELL_PCH or URA_PCH state to reduce battery consumption. Upon receiving the SCRI, the RNC can release the signaling connection and put the UE into idle mode, or the RNC can maintain the signaling connection and put the UE to CELL_FACH or CELL_PCH/URA_PCH state. RSVDBIT1_BIT29 of the RsvdPara1 parameter in the SET URRCTRLSWITCH command controls the UE through CELL_FACH to CELL_PCH/URA_PCH or directly to CELL_PCH/URA_PCH. These procedures can reduce battery consumption, depending on the UE capability and feature activation on the RNC. By default, the RNC puts the UE into idle mode. A UE setting up PS services in idle mode consumes more signaling resources than that in the CELL_PCH or URA_PCH state. If there are a large number of UEs transited between idle mode and CELL_DCH state, signaling storms may occur. The EFD feature puts UEs into the CELL_FACH or CELL_PCH state to reduce signaling resource consumption and eliminate signaling storms.

Huawei provides a comprehensive end-to-end solution based on network characteristics to respond to network challenges. EFD is one component of the solution. This feature alone is not enough to eliminate signaling storms caused by intelligent UEs. However, when applied with professional services, EFD can be used to optimize the quality of service (QoS) for the entire network.

Consult Huawei engineers to receive the appropriate parameter settings for this feature along with other comprehensive professional support. Do not configure the EFD parameters without Huawei professional technical support. Inappropriate parameter settings may lead to network failures.

The UEs on a live network can be divided into three types:

UEs that do not send SCRI messages because there is no PS data to be transmitted.

Pre fast dormancy UEs. This type of UE does not read the T323 information element (IE) carried in the system information block type 1 (SIB1) message. After PS data transmission is complete, this type of UE sends an SCRI message to the RNC, but the SCRI message does not carry the IE Signaling Connection Release Indication Cause. Both T323 and Signaling Connection Release Indication Cause are introduced in 3GPP Release 8.

R8 fast dormancy UEs. This type of UE reads the T323 IE carried in the SIB1 message and sends an SCRI message to the RNC after PS data transmission is complete. The SCRI message carries the IE Signaling Connection Release Indication Cause that is set to "UE Requested PS Data session end."

The T323 IE carried in the SIB1 message controls the frequency at which the R8 fast dormancy UEs send SCRI messages with the IE Signaling Connection Release Indication Cause set to "UE Requested PS Data session end". The T323 timer starts after an SCRI message is sent by the R8 fast dormancy UEs, and the second SCRI message with the IE Signaling Connection Release Indication Cause set to "UE Requested PS Data session end" can be sent only after the T323 timer expires.

The EFD feature applies only to the pre fast dormancy UEs and R8 fast dormancy UEs. Users can configure EFD to be enabled for only the pre fast dormancy UEs or R8 fast dormancy UEs.

When this feature is disabled, the RNC releases the signaling connection and puts the UE into idle mode after receiving the SCRI message regardless the UE types.

When this feature is enabled, the RNC performs different processing based on the UE type:

For the pre fast dormancy UEs, the RNC checks for compatibility issues after receiving an SCRI message. If there are no compatibility issues, the RNC puts the UE into the CELL_FACH or PCH state. If there is a compatibility issue, the RNC puts the UE into idle mode.

For the R8 fast dormancy UEs, the RNC puts the UE into the CELL_FACH or PCH state after receiving an SCRI message.

Some pre fast dormancy UEs may have compatibility issues after moving to the CELL_FACH, CELL_PCH, or URA_PCH state. As a result, new services cannot be initiated. This feature has been tested by using iPhones and no compatibility issue occurred.

Enhanced Fast Dormancy 3 Technical Description



3-1

3 Technical Description

When there is no PS data to be transmitted, the intelligent UE sends the RNC an SCRI message to request the UTRAN to release the signaling connection. This procedure saves power. In addition, the UE periodically sends heartbeat messages to the core network, for example, to check for new mails on the mail server. If the EFD feature is disabled, the RNC releases the signaling connection and puts the UE into the idle state. In this case, sending heartbeat messages leads to the procedures for RRC connection setups, authentication, encryption, and RAB setups. These procedures increase the RNC signaling processing load.

EFD addresses this problem. With EFD, the RNC transits a UE to the CELL_FACH or PCH state instead of idle mode upon receiving an SCRI message from the UE. In this case, when the UE periodically sends heartbeat messages, the signaling procedure between the UE and RNC is simplified because the RRC connection is maintained. As the number of signaling exchange messages decreases, significant CPU resources can be saved for the RNC, and the UE consumes about the same low amount of battery power as a UE in idle mode.

This feature is controlled by FAST_DORMANCY_SWITCH of the PROCESSSWITCH parameter in the SET URRCTRLSWITCH command.

Figure 3-1 shows the signaling processing procedures for pre fast dormancy UEs and R8 fast dormancy UEs before and after EFD is enabled.

Enhanced Fast Dormancy 4 Identifying Fast Dormancy UEs



4-1

4 Identifying Fast Dormancy UEs

The RNC identifies the pre fast dormancy UEs and R8 fast dormancy UEs using the following mechanisms:

R8 fast dormancy: The T323 parameter that can be set in the SET UCONNMODETIMER command is sent to the UE by the SIB1 message. The R8 fast dormancy UEs send an SCRI message with the IE Signaling Connection Release Indication Cause set to "UE Requested PS Data session end" after PS data transmission is complete. The RNC identifies the R8 fast dormancy UEs by reading the value of IE Signaling Connection Release Indication Cause.

This mechanism is standardized by 3GPP Release 8. Some Release 6 and Release 7 smartphones, such as iPhones, have been enabled with the fast dormancy function defined in Release 8.

Pre fast dormancy: The RNC identifies the pre fast dormancy UEs using the Type Allocation Codes (TACs).

This mechanism, which is not standardized, is used for the early proprietary implementations of fast dormancy.

The international mobile equipment identity (IMEI), which consists of 14 decimal digits and one check digit, contains TAC and SNR. TAC indicates a particular type of device that has been approved by a national GSM/WCDMA approval body. SNR is the serial number identifying the UE. The structure of the IMEI, which is shown as follows, is specified in 3GPP TS 23.003.

TAC (8bit) SNR (6bit) Spare (1bit)

To identify pre fast dormancy UEs, FD_TAC_MATCH_SWITCH of the PROCESSSWITCH parameter on the RNC side needs to be turned on. The TAC parameter has been set for the pre fast dormancy UEs by the ADD UIMEITAC command after FastDormancy is ebabled. The RNC checks the TAC of the IMEI in the IDENTITY REQUEST message. If the TAC is included in the EFD list, the UE can use EFD.

Enhanced Fast Dormancy 5 State Transitions for Fast Dormancy UEs



5-1

5 State Transitions for Fast Dormancy UEs

When EFD is disabled, upon receiving an SCRI message from a UE, the RNC releases the UE’s RRC connection. The EFD switches are specified by the RNC-level subparameter FAST_DORMANCY_SWITCH of the parameter PROCESSSWITCH.

When EFD is enabled, state transition procedures vary according to the UE type as follows:

For R8 fast dormancy UEs and pre fast dormancy UEs in EFD list:

− If the RNC received the SCRI, The RNC transfers the UE to CELL_FACH or CELL_PCH/URA_PCH. The RSVDBIT1_BIT29 subparameter of the RsvdPara1 parameter in the SET URRCTRLSWITCH command and FD_TAC_FORCE_D2F_SWITCH of PROCESSSWITCH in the ADD UIMEITAC command controls whether the UE moves to CELL_FACH or CELL_PCH/URA_PCH together.

− After PS data transmission is complete, If UE is in CELL_DCH, the PS inactivity timer (PsInactTmrForFstDrmDch) for EFD in CELL_DCH is started. If the PS inactivity timer for EFD in CELL_DCH expires, the RNC transfers the UE to CELL_FACH or CELL_PCH/URA_PCH.

− After PS data transmission is complete, If UE is in CELL_FACH, the PS inactivity timer (PsInactTmrForFstDrmFach) for EFD in CELL_FACH is started. If the PS inactivity timer for EFD in CELL_FACH expires, the RNC transfers the UE to CELL_PCH/URA_PCH.

− If UE is transferred to CELL_PCH/URA_PCH, the PS inactivity timer (PsInactTmrForPreFstDrm) is started. If the PS inactivity timer for EFD in CELL_PCH expires, the RNC transfers the UE to IDLE. The value of this timer should be less than or equal to that of T305, preventing the UE from being always in the CELL_PCH state and unable to enter the idle state.

− If UE is in CELL_PCH/URA_PCH and has something to send and the condition for P2D/U2D is not satisfied, the RNC instructs the UE to enter the CELL_FACH state.

− TAC-based P2D/U2D transitions. That is, when FD_P2D_SWITCH of PROCESSSWITCH in the ADD UIMEITAC command is turned on, a P2D/U2D transition starts if the UE's TAC is identical with the TAC added to the EFD list by running the ADD UIMEITAC command and the UE experiences uplink data transmission or has a paging response in the PS domain.

− For details about P2D/U2D transitions related to FACH congestion, see section 4.3 "FACH Congestion Control" in Flow Control Feature Parameter Description.

− If UE is in CELL_FACH and send messages whose traffic volume is higher than FastDormancyF2DHTvmThd, The RNC will transfer the UE from CELL_FACH to CELL_DCH.

− The main factor for triggering the D2I transitions is FACH congestion. For details about state transitions due to FACH congestion, see section 4.3 “FACH Congestion Control” in Flow Control Feature Parameter Description.

− For details about P2U/U2U/D2D/CPC/E-FACH and D2F/F2P based on 4B event state transitions, see State Transition Feature Parameter Description.

For pre fast dormancy UEs not in EFD list:

− If the RNC received the SCRI, the RNC transfers the UE to IDLE state.

− The state transition for pre fast dormancy UEs not in EFD list is the same to ordinary UEs. For details, see State Transition Feature Parameter Description.

− For details about state transitions due to FACH congestion, see section 4.3 “FACH Congestion Control” in Flow Control Feature Parameter Description.

Figure 5-1 shows the state transitions for R8 fast dormancy UEs and pre fast dormancy UEs in EFD list.

Type Description

D2P

D2U

D2F

F2P

F2U

D2P indicates a transition from CELL_DCH to CELL_PCH, F2P from CELL_FACH to CELL_PCH, and D2F from CELL_DCH to CELL_FACH.

The RNC starts the PS inactivity timer for fast dormancy when inactivity on PS data is detected.

PsInactTmrForFstDrmDch specifies the PS inactivity timer for CELL_DCH.

PsInactTmrForFstDrmFach specifies the PS inactivity timer for CELL_FACH.

PsInactTmrForPreFstDrm specifies the PS inactivity timer for CELL_PCH.

If the UE is a fast dormancy UE and is not processing CS services, when the PS inactivity timer for fast dormancy expires or the RNC receives an SCRI message or 4B event from the UE, the UE changes states as follows:

For a UE in the CELL_DCH state:

− If RSVDBIT1_BIT29 of RsvdPara1 in the SET URRCTRLSWITCH command is turned off or FD_TAC_FORCE_D2F_SWITCH of PROCESSSWITCH in the ADD UIMEITAC command is turned on , the RNC triggers a D2F state transition.

− If RSVDBIT1_BIT29 of RsvdPara1 in the SET URRCTRLSWITCH command is turned on and FD_TAC_FORCE_D2F_SWITCH of PROCESSSWITCH in the ADD UIMEITAC command is turned off, the RNC triggers a D2P/D2U state transition.

The D2F and F2P state transitions are recommended for the following reasons:

During an IOT test, some terminal issues occur. Occasionally, terminals fail to establish services after a transition from CELL_DCH to CELL_PCH/URA_PCH. This failure has a bad impact on user experience.

Compare with a state transition from CELL_DCH to CELL_FACH and then to CELL_PCH/URA_PCH, the state transition from CELL_DCH to CELL_PCH/URA_PCH does not improve the network performance or user experience.

Some terminals send CELL UPDATE message to transfer data immediately after a state transition from CELL_DCH to CELL_PCH/URA_PCH, which increases the signaling messages and leads to a heavy load on the Uu interface.

For a UE in the CELL_FACH state, the RNC trigger an F2P state transition.

D2I D2I indicates a transition from CELL_DCH to idle.

D2I is mainly used for FACH congestion. For details about state transitions due to FACH congestion, see section 4.3 “FACH Congestion Control” in Flow Control Feature Parameter Description.

P2I/U2I P2I/U2I indicates a transition from CELL_PCH to idle.

If the UE is in the CELL_PCH state, when the PS inactivity timer for fast dormancy (specified by PsInactTmrForPreFstDrm) expires, the RNC releases the UE's RRC connection and then the UE enters idle mode.

P2D

U2D

− TAC-based P2D/U2D transitions. That is, when FD_P2D_SWITCH of PROCESSSWITCH in the ADD UIMEITAC command is turned on, a P2D/U2D transition starts if the UE's TAC is identical with the TAC added to the EFD list by running the ADD UIMEITAC command and the UE experiences uplink data transmission or has a paging response in the PS domain.

− For details about P2D/U2D transitions related to FACH congestion, see section 4.3 "FACH Congestion Control" in Flow Control Feature Parameter Description.

Type Description

P2F

U2F

P2F/U2F indicates a transition from CELL_PCH/URA_PCH to CELL_FACH.

When the UE has something to send and the condition for P2D/U2D is not satisfied, the RNC instructs the UE to enter the CELL_FACH state.

F2D F2D indicates a transition from CELL_FACH to CELL_DCH.

When a fast dormancy UE is in the CELL_FACH state, When the fast dormancy UE send messages whose traffic volume is higher than FastDormancyF2DHTvmThd, The RNC will transfer the UE from CELL_FACH to CELL_DCH. The FastDormancyF2DHTvmThd is a new threshold of event 4a for fast dormancy UE, This threshold is set to bigger than traffic volume of most heartbeat messages so that to prevent state transitions from being triggered by a small number of heartbeat messages.

6 Engineering Guidelines

6.1 When to Use Enhanced Fast Dormancy

The EFD feature is recommended for scenarios where the proportion of intelligent UEs is high, leading to a high CPU load on SPU boards in the RNC and on baseband processing boards in the NodeB. This feature reduces the Uu, Iu, and Iub signaling, uplink and downlink channel element (CE) consumption, and CPU load.

6.2 Feature Deployment

For details about how to activate, verify, and deactivate this feature, see Configuring Enhanced Fast Dormancy in Feature Activation Guide.

principles that RNC judges UE whether to accept the CR2284R1 are as follows: R5 and above UE accepts the CR; R99/R4 UE, if it receives the START LIST value from RB SETUP COMPLETE,RNC figures that UE accepts the CR; R99/R4 UE, if it only receives the START value from RB SETUP COMPLETE,RNC figures that UE does not accept the CR; when it is not checked, whether RNC accept the CR or not is according to CR2284R1_SWITCH. The relations between these two switches CR2284R1_SWITCH and CR2284R1_COMPATIBLE_SWITCH are as follows:

(1)CR2284R1_COMPATIBLE_SWITCH is checked, RNC is self-compatible, so the CR2284R1_SWITCH is invalid;

(2)CR2284R1_COMPATIBLE_SWITCH is not checked, the CR2284R1_SWITCH is valid.

13)COMBINE_OPERATION_DRD_SWITCH.

When it is on, RNC will not reject the message RB SETUP CMP without the IE active time.

14)UL_INTER_PROTECT_SWITCH.

When the switch is off, RNC will not do integrity protection check for uplink RRC messages.

15)FAST_DORMANCY_SWITCH.

When it is checked, RNC will apply FAST DORMANCY function.

16)SYS_HO_IN_CIPHER_SWITCH.

When it is checked, don't receive the encrypted ability information from RELOC REQ ,default configured of encrypted parameter are UIA1 and UEA0.

17)PTT_EARLY_TRANS_SWITCH_OFF.

When it is checked, PTT user will not apply the early transmission function, otherwise, PTT user will apply the early transmission function.

18)UPLINK_MDC_ENHENCEMENT_SWITCH.

This switch has become invalid.

19)NODEB_PRIVATE_INTERFACE_SWITCH.

None None Meaning:1) FD_P2D_SWITCH (TAC-Level P2D Control Switch)

When the switch is turned on, state transition from CELL_PCH/URA_PCH to CELL_DCH of a UE is triggered if the following conditions are met:

1. The TAC of the UE is the same as that configured on the RNC.

2. The UE is in the CELL_PCH or URA_PCH state, and the RNC receives a CELL UPDATE message containing a cause value of "uplink data transmission" or "PS paging response."

When the switch is turned off, state transition from CELL_PCH/URA_PCH to CELL_DCH is not triggered by the CELL UPDATE message containing "uplink data transmission" or "PS paging response."

In this case, however, the state transition can be triggered by other factors in the system. For example, if the UE is in the CELL_PCH or URA_PCH state, the state transition to CELL_DCH can be triggered by a CS terminated call.

2) FD_TAC_FORCE_D2F_SWITCH (TAC-based D2F Switch for UEs Supporting Fast Dormancy)

When the switch is turned on, state transition from CELL_DCH to CELL_FACH is forcibly performed on the UE with the corresponding TAC and supporting fast dormancy.

When the switch is turned off, CELL_DCH to CELL_PCH/URA_PCH state transition is forcibly performed on the UE with the corresponding TAC and supporting fast dormancy.
